* Add `random-state-from-platform' and `scm_i_random_bytes_from_platform'...* libguile/random.c (scm_random_state_from_platform): New procedure. (scm_i_random_bytes_from_platform): New internal function. * libguile/random.h (scm_random_state_from_platform, scm_i_random_bytes_from_platform): Add prototypes. * doc/ref/api-data.texi (Random): Add documentation. Mark H Weaver2012-01-211-0/+3
* Fix the range of `random' on 64-bit platforms...For > 32 bit integers still in the fixnum range, scm_random() would return random numbers with a lower range than specified. * libguile/random.c (scm_i_mask32): New static inline function. (scm_c_random): Use `scm_i_mask32'. (scm_c_random64): New function, 64-bit variant of scm_c_random. (scm_random): Use `scm_c_random64' instead of forming the 64-bit random number in a bogus way. * libguile/random.h: Added `scm_c_random64'. Andreas Rottmann2010-08-011-0/+1
* 64-bit random fixes...* libguile/random.c (scm_random): Fix generation of inum randoms with more than 32 bits. * libguile/random.h (scm_t_rstate): Fix a comment. Andy Wingo2010-07-271-1/+1
* rstates point to rngs...* libguile/random.h (scm_t_rstate): Include the rng in the rstate, so we can actually have multiple rngs. Instead of reserved0 / reserved1, reserve a double explicitly for scm_c_normal01. (scm_c_uniform32): Change to call the rstate's rng. * libguile/random.c: Change to access an rstate's rng through its rng pointer. (scm_c_normal01): Instead of a flag and a next double, just check that the double is equal to 0.0. Excluding one value shouldn't affect the distribution, right? Andy Wingo2010-07-261-3/+3
* refactor datum->random-state / random-state->datum...* libguile/random.c (scm_t_i_rstate): Move here from random.h, along with prototypes for functions (scm_i_uniform32, scm_i_init_rstate, scm_i_copy_rstate): Change to take a stock scm_t_rstate as an arg, and cast it. This way we don't cast the pointers below. (scm_i_rstate_from_datum, scm_i_rstate_from_datum): Same and rename from scm_i_init_rstate_scm / scm_i_expose_rstate. (scm_c_rstate_from_datum): Rename from scm_c_make_rstate_scm. (scm_datum_to_random_state, scm_random_state_to_datum): Rename from scm_external_to_random_state and scm_random_state_to_external. (scm_init_random): Remove casts. * libguile/random.h (scm_t_rng): Rename init_rstate_scm, expose_rstate vmethods to from_datum, to_datum. Remove internal definitions. Rename to scm_c_rstate_from_datum, and provide scm_random_state_to_datum and scm_datum_to_random_state. Andy Wingo2010-07-261-19/+5
* low-level RNG interfaces deal in scm_t_uint32, not unsigned long...* libguile/random.h (scm_t_rng): random_bits returns a scm_t_uint32. (scm_i_uniform32, scm_t_i_rstate): Internal RNG returns a scm_t_uint32, as advertised, instead of unsigned long. (scm_c_random): Return a scm_t_uint32 instead of an unsigned long. * libguile/random.c (scm_i_uniform32, scm_i_init_rstate_scm): (scm_i_expose_rstate, scm_c_random, scm_c_random_bignum, scm_random) (scm_init_random): Adapt types to match implementation. Andy Wingo2010-07-261-5/+5
* Allow exposing of random number generator state...Now the random number generator state can be obtained in external (i.e. `read'/`write'-able) form via the new procedure `random-state->external'. An externalized state can be reinstantiated by calling `external->random-state'. * libguile/random.c (scm_i_init_rstate_scm, scm_i_expose_rstate): New internal functions. * libguile/random.c (scm_c_make_rstate_scm, scm_external_to_random_state, scm_random_state_to_external): New public functions. * libguile/random.h: Add prototypes for the above functions. * libguile/random.h (scm_t_rng): Add new fields `init_rstate_scm' and `expose_rstate'. * libguile/random.c (scm_init_random): Initialize the new fields in `scm_the_rng'. Andreas Rottmann2010-07-261-1/+6

(scm_gensym): Generate only the number suffix in the buffer, just string-append the prefix. Marius Vollmer2004-08-191-3/+3
* Use SCM_SMOB_* instead of SCM_CELL_* as appropriate. Use...SCM_SMOB_FLAGS and SCM_SET_SMOB_FLAGS instead of accessing the zeroth word directly. Use SCM_SMOB_PREDICATE as appropriate. Marius Vollmer2004-05-061-2/+2
